An emulator-based forecasting on astrophysics and cosmology with 21 cm and density cross-correlations during EoR
Barun Maity
The 21 cm signal arising from fluctuations in the neutral hydrogen field, and its cross-correlation with other tracers of cosmic density, are promising probes of the high-redshift…

Measuring the IGM correlation length at 5<z<6.1: a fast change at the end of Reionization
Benedetta Spina, Sarah E. I. Bosman, Barun Maity +1
The Lyman- forest of high redshift quasars is a powerful probe of the late stages of the Epoch of Reionization (EoR), particularly through the presence of Gunn-Peterson troughs.…

Efficient Modelling of Lyman-α opacity fluctuations during late reionization epoch
Barun Maity, Frederick Davies, Prakash Gaikwad
The Lyman- forest opacity fluctuations observed from high-redshift quasar spectra have been proven to be extremely successful in order to probe the late phase of the reionizatio…
